Bolometric luminosity variations in the luminous blue variable AFGL2298
Abstract
Aims: We characterise the variability in the physical properties of the luminous blue variable
Methods: In conjunction with published data from 1989-2001, we have undertaken a long term (2001-2008) near-IR spectroscopic and photometric observational campaign for this star and utilise a non-LTE model atmosphere code to interpret these data.
Results: We find
